AI Technical Summary
In high-temperature and high-airflow environments, the surface potential distribution of DC through-wall bushings is uneven, leading to charge accumulation and the risk of discharge breakdown. Existing measurement methods cannot accurately calculate the bushing surface potential.
A rotary passive electrostatic meter was used for calibration. Electric field data and potential data were mapped by mathematical function expressions. A high-temperature and high-airflow simulated environment was built to measure the surface electric field of a real DC through-wall bushing and determine the potential data.
Accurate calculation of the surface potential of DC through-wall bushings under high temperature and high airflow conditions improves the operational reliability and safety of the bushings and avoids discharge breakdown faults caused by charge accumulation.
